Xiaomi's new in-display fingerprint sensors have a much bigger active area - The Verge

For me, finger print sensor at the back is enough. The reason is when you ar ebeing forced to open your phone, it would be easy for other people to have your phone opened. I don't see the need for an entire display to be opened with your fingerprint. I know Huawei already put up that feature followed by Oppo. I won't be using such feature if ever I have such.
